BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handbag that can be stored in small portions and a method for efficiently producing the handbag.

[0002]

2. Description of the Related Art Handbags made of pulp paper or synthetic paper are simple and widely used for shopping.

[0003] These handbags are made of a single sheet-like material such as pulp paper or synthetic paper mainly made of polypropylene, polystyrene, polyvinyl chloride or the like as described above, and this is made by a bag making machine. It is formed into a folded bag sequentially.

By the way, as a form of the handbag, a square bottom type having a gusset on a side surface is mainly used.
It is common to attach a string or handle for carrying to the upper opening edge.

[0005]

However, although the above-mentioned conventional handbag can be automatically formed by a bag making machine, it has only one storage portion, that is, only one storage portion, so that small items can be sorted out. There was a drawback that it could not be stored.

[0006] On the other hand, there is a device such as a bag or a wallet having a plurality of storage sections, but since these pieces are sewn with a plurality of leathers, it has been very difficult to automate the production.

[0007]

In order to solve such a problem, the present invention has three storage portions formed of one sheet-like member and having an upper portion opened as an opening. A handbag having a lid that can be closed and having a gusset formed on a side portion is provided.

Further, the present invention has three storage portions formed of a single sheet-like member and having an upper portion opened as an opening portion, a lid portion capable of closing the opening portion, and a gusset on a side portion. A method of manufacturing a formed handbag,
A protruding piece that forms the lid is formed on substantially half of one side of the sheet-shaped member, and one end of two sides of the sheet-shaped member orthogonal to the protruding piece is folded in a predetermined width, and the folded back is turned inward. Is formed, and one end of the sheet-like member is folded along the fold outside the fold to form an adhered piece that overlaps with the fold. To form a fold facing one end side, and then fold the sheet-like member along a fold outside the fold formed in the center portion to polymerize and bond the other end of the sheet-like member and the sticking piece. Then, the sheet-like member is folded so that both sides of the opening face each other, and both edges perpendicular to the opening are superimposed and adhered to each other.

[0009]

According to the handbag of the present invention, the bag has three storage portions formed of one sheet member and having an upper portion opened as an opening, and has a lid portion capable of closing the opening, and a side portion. Since the gussets are formed in the sections, small items can be stored in each storage section in small pieces, and the width of the opening can be greatly increased, so that the storage capacity is improved.

[0010]

Embodiments of the present invention will be described below in detail with reference to the drawings. First, FIG. 1 shows a handbag according to the present invention.
The handbag 1 is a paper or synthetic resin bag made of one sheet-like member. As shown in the figure, the handbag 1 has a rectangular shape, the sides 2 and 2 and the bottom 3 are sealed, and the top is opened as an opening 4.

In particular, the back surface 5 protrudes from the opening edge 4a, which is the uppermost end of the side portion 2, and serves as a lid portion 6. The back surface 5 is provided with a fold line N at a portion that coincides with the opening edge 4a or at a position slightly above the fold line 4a, and the cover 6 is fed inward at the position of the fold line N. Thus, the opening 4 can be closed.

Gussets 8, 8 folded into a mountain shape are attached to the side portions 2, 2 so that the width of the opening 4 can be greatly increased. Further, two membrane walls 10 and 11 are provided between the front surface 9 and the back surface 5 so that the inside of the handbag 1 can be divided into three storage portions 13a, 13b and 1
3c. In particular, the film walls 10 and 11 are provided with gathers 14 and 14 at the center, respectively, and the opening edges 4a, 4b and 4c are provided with steps.

Therefore, each of the storage sections 13a, 13b, 13c
Can be stored by classifying small items and different types of documents, etc., and in particular, a large amount can be stored by being concentrated in a specific storage portion as much as the gather 14 is extended, and each opening edge 4a, 4b, Since there is a step in 4c, it is possible to smoothly carry in and out the stored items. Here, it is preferable that the lid portion 6 is folded in two to increase the strength and is made thick.
FIG. 2 shows a cross section of the handbag 1.

Here, the handbag 1 constructed as described above is used.
A method of manufacturing the device will be described. FIG. 3 is a plan view of the sheet-like member showing the state in which the handbag 1 is expanded. , T2 are formed in a protruding state. The sheet member S is made of pulp paper or synthetic paper mainly made of synthetic resin.

In such a sheet-like member S, first, the protruding piece T1 is substantially folded in two at the location of the folding line N1, and the folded portion is adhered with an adhesive such as hot melt. Before and after this, as shown in FIG.
One end S1 of the sheet-like member S, which is closer to the protruding piece T1 of the two sides orthogonal to the protruding piece T1, is folded at a location of the folding line N2 by a predetermined width (about 15 to 60 mm), and is also folded at a location of the folding line N3. To form a fold P with a width of about 5 to 20 mm facing inward by folding back a certain width (about 10 to 40 mm)
One end S1 along the fold outside the fold P, that is, the fold line N2, is fixed at a predetermined width (5 to 20 m) at the fold line N4.
m) to form an adhesive piece E that is folded and polymerized with the fold P.

On the other hand, as shown in FIG. 4B, a substantially central portion of the sheet-like member S is fixed at a predetermined width (15 to
(About 60 mm) and folded at a predetermined width (about 10 to 40 mm) at the fold line N6 to form a fold Q having a width of about 5 to 20 mm facing one end S1 side.
Between the fold Q and the other end S2 of the sheet-like member, the sheet-like member S is folded at the location of the folding line N7,
Further, a gather R having a width of about 5 to 20 mm is formed by folding back at the location of the folding line N8.

Next, as shown in FIG.
The sheet-like member S is folded along the folding line N5 at the location of the folding line N9, and the other end S2 of the sheet-like member S and the sticking piece E are overlapped and adhered.

Incidentally, an adhesive such as hot melt is applied to a portion of the adhesive piece E which is to be polymerized with the other end S2 immediately before the polymerization. Of course, when the material such as synthetic paper is mainly made of synthetic resin, the material may be heat-sealed after polymerization, but at this time, it is important to prevent the sticking piece E and the fold P from fusing. .

Either of the two folds P and Q may be formed first, but they may be formed simultaneously. Further, the gathers R to be gathers 14 shown in FIG. 1 may be formed before or after the folds P and Q.

By the way, when the other end S2 and the sticking piece E are bonded, the upper and lower sides in FIG. 4C are open as openings F, F.

Therefore, the sheet F is formed so that the opening portions F are opposed to both sides thereof, and in particular, the opening edge 4b is shifted to the side opposite to the opening edge 4a with respect to the opening edge 4a as shown in FIG. The member S is folded at the position of the folding line N10, and both edges G, G (both ends of the surface X in FIG. 4C) orthogonal to the opening F are overlapped and adhered.

It is to be noted that an adhesive such as hot melt is applied to both edges G, G immediately before folding the sheet-shaped member S. Of course, when the material such as synthetic paper is mainly made of synthetic resin, it is possible to perform heat fusion after folding, but at this time, the fold P or the fold Q which is superposed with the both edges G, G is formed.
It is important to prevent fusing.

In this way, the handbag 1 as shown in FIG. 1 can be obtained.
Can be used as a wallet or various card holders by folding the protruding piece T1 at the location of the folding line N.
